'ful Improvement in Shutteielrlinges, of which the following is aspecification. i

'This improvement relates to the class oiauto-y mat-iclockingsl'uittenhinges.

The object of the invention is to furnish a simple and reliablelock-hinge, easily molded and cast, requiring very little fitting, andadaptable to all shutters.

The drawings herewith, which form a part of this specilication, are sofully detailed that an expert will easily comprehend them. Similarletters designate similar parts throughout the same. A

Figure l is a front elevation of my improved locking-hinge. Fig. 2 is arear view of the same. Fig. 3 is a sectional plan on the linex :c ofFig. l. il is a simple plan of Fig. 2. Fig. 5 is a front and edge viewof the detached \vindow-fra1ne leaf. Fig. 6 is a front and edge viewofthe detached shutter-leaf. Fig. 7 is a plan and end view oi' thelatch-pocket cap. Fig. S is an elevation and reverse plan of thehinge-latch. Fig. 9. is an elevation and end view of an alternativelatch.

B represents the shutteuhinge leaf, B", thepintle-soeliet; B2, the latch-keeper; B, a notch cut out of the inneredge oi' the leaf. @represents the latch, C', the latch-lifter; C,easement to facilitate rising upon the keeper; C, fulerum of latch; 6*,grip of alternative latch, D, screw-holes or screws.

I am well aware that I am not the first to construct shutter -hiugesautomatic or selfpattern is easily changed into my self-locking deviceas follows: The frame-leaf A has a central oblong piece' cut out of thesame, as at A, and a ShelLpocket, A`, is soldered upon the back, and soarranged relative to the leaf that it is molded without the use ofcores. A reenforee, A, is also placed, as shown in Figs. 2 and 4, toprevent overreaching of the shutter. The latch-pocket AL' is providedwith seats, as shown, for the cap, which prevents binding of the latch.The leai is provided with the usual screw-holes, l), the central screw,(Y, in this leaf actingas the iulcrum for the latch. The pintlehoss Aand pintle A" may be enlarged, if desired, so that the whole may be ofcast metal, or the pintle may he of wrought-iron- The shutter-leaf B hasa central notch, B, cut out ofthe same, and hack of it is placed thelatch-keeper B2, constructed as shown.

to suit the pintle of cast or wrought iron. The notch in the leaf admitsof the molding of'the same with its keeper without the use of cores. Thelatch C is a plain casting, having a lifter, G', and the face of thelatch at the outer end, G2, rounded or eased oli, so as to ride upcn thekeeper incline when the shutters are ythrown hack. The cap of thelatch-pocket A" rests upon its seat, and the outer end has a projectingpiece which closes the pocket at the edge of the hinge. lt has a centralcountersink-hole, CY", for the lateli-fulcrum screw. Fig. 9 shows alatch, which if used will do away with the keeper. The head or. grip C*on opening and throwing back the shutter would protrude through the leafB, and dropsame in place. The head C* in this case would act in place ofthe lifter C', which could he dispensed with. I give preference,however, to the arrangement of latch shown iii Fig. 8. In assembling thehinge, the latch C is placed inthe pocket Al of the leaf A and concealedwith the cap Ai. The leaf B is then held at right angles with the leafA, and the socket B is slid down over the pintle Al and then folded overAupon A. In applying the hinges, the leaf A or B is iitted, as usual,.flush with the inner face, and secured with screws D, as with ordinaryhinges', the central screw, C3, on the leaf A passing through the cap A,latch C,

ping over the body thereof would lool; theu The pintle-socket B iseither drilled or cored i IOO l. In an automatic-lookin g shutter-hi nge,thc

combination of a perforated and pocketed leaf, A, provided with apocket-cap, A", and a rcenforce, A, pintle-boss A, and pintle A4, with aleaf, B, having a pintle-socket, B, latchkeeper B2, and notch B, adaptedto be automatically locked in'an opened position by the latch C,fulcrumed in the pocket A'-y in the p screw C, and arranged to ride uponand lock within the keeper B2, and to be disengaged therefrom by thelifter C, substantially as shown, and for the purpose set forth.

2. In an automatic locking-hi nge, the frameleaf A, provided With apocket, A2, having seats therein for a cap, A, the cap provided with anoffset closing the out edge of the pock-A et, both in combination withthe latch C by the fulcrum-screw C3 and with the shutter. 2

3. In an automatic locking-hinge, the shutter-leaf B, provided with akeeper, B, and 3o pintle-socket B, having an inner edge notch, B, cuttherefrom to disclose the keeperand permit the molding of the sameWithout the use of cores, and in combination with the frame-leaf A, byp'intle A, and latch C, sub- 3 5 stantially as and for the purpose setforth.
